FourSquare.com is one of those social networks where users “check in” to tell friends where they are, and earn “virtual badges” (meaning not real badges) for frequenting various places oftener than their friends. The site is being used on some college campuses for freshman orientations and in business for employee orientations. You give everyone a map and ask them to check in at spots around campus. The drawback? Employees might think you’re spying on them. Ideally, the boss would create a temporary FourSquare account that expires after the orientation is over. In any event, you aren’t sharing with the whole world, just those on your list. Which is why FourSquare has told the website PleaseRobMe.com, which mocks the idea, to please shut up.
